![r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B%20k%20%5BNO_2%5D%5E2%20%5BF_2%5D%7D%7B%5BNO_2F%5D%7D)
Explanation:
From the question we are told that
The formation mechanism is


The overall balanced equation is

We combined the first reactant and the last product and the balanced the number of mole
The observable rate law is
![r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B%20k%20%5BNO_2%5D%5E2%20%5BF_2%5D%7D%7B%5BNO_2F%5D%7D)
This rate law is derived from the balanced chemical equation
Yes... the change of direction results in acceleration

Answer: inhibitor
Explanation:
Enzymes have a shape that closely resemble that of the substrate hence they fit into the substrate by lock and key mechanism. The activity of the enzyme hinges on its similarity with the substrate in shape. Any other molecule similar to the shape of the substrate can fit into the substrate thereby preventing the enzyme from locking with the substrate. Such substances are called inhibitors. They decrease the activity of an enzyme.
